A sprinkler that will be used in drip irrigation
At the junction of hot sand and blue sky, there is a large low fruit tree that can not be seen. The Israeli farmer Abu Tambi pointed at the fruit tree and said: "Our biggest problem now is the lack of labor and the fruit trees can only grow so much."
Abu Tambi said that ten years ago, he could only plant cotton and some inedible plants in the Negev desert, and the days were tough. Later, the desert appeared better "Mediterranean", combined with intelligent drip irrigation technology, now not only "what can species", and grow high quality fruit more popular with Europeans, through export trade, he earned a lot Last year, money bought a new agricultural machine. Abuttabha's rite of wealth just shows the tip of the iceberg of Israel's smart water management capabilities. Behind this little story, in fact, contains the Israelis how to "waste water regeneration" in the desert, how to "water into gold," a big cause.
Recently, the reporter of Guangzhou Daily penetrated into the desert in Israel and witnessed how the Israelites made use of the desert and waste water to turn the desert into a "Mediterranean" course.
This year marks the 25th anniversary of the establishment of diplomatic relations between China and Israel. From June 6 to June 6, the delegation of Guangdong Province visited Israel to attend the China (Guangdong)-Israel Economic and Trade Cooperation and Exchange Conference. The water resources management, wastewater treatment, water environment protection, has been an important issue of urban environmental governance in Guangzhou. Under the background of deepening economic and trade cooperation, Israel's well-developed water resources management technology is exactly what Guangdong needs to learn from.
Desert agriculture:
Wastewater irrigates good quality fruit
Israel is slightly higher latitude in Guangzhou, located in the subtropical. Land area slightly larger than Beijing, but nearly half of desert areas, year-round rain. Although still in June, the sun is already hot. Reporter from its second largest city of Tel Aviv, all the way south, came to the Negev desert.
The arid Negev desert not only has rough gravel, but also many thriving settlements. In the southwestern Negev desert there are some special forms of settlement that develop agriculture through collective farming on private leased land. Near one of the settlements reservoirs, the reporter saw the farmer Abu Tambi, a middle-aged, great farmer who looked over and over from time to time to the small kingdom on the edge of his reservoir - a large green forest that was not yet ripe Pomegranate.
Israel's desert reservoir is a local scene: a huge blue artificial lake appeared in the vast hot sand, clear water, eyes full of cool. Aqua blue, comparable to the Mediterranean Sea on the edge of Tel Aviv.
"The water depth is about 15 meters." The technical director told reporters, "Inside are treated wastewater." Reporters learned that such a "reclaimed water reservoir" in the Negev desert there are many, supporting a lot of settlements Agriculture. The treated wastewater, although not used as drinking water, is suitable for irrigation. To date, the treated wastewater has been the most important source of agricultural water in the desert of Israel.
In many less-developed countries, irrigating untreated wastewater is not uncommon, but harmlessly used, at the core of which is the "decontamination" of wastewater, the removal of heavy metals from water quality, and the pollution of the land, which is exactly where the Israelites are . For waste water as irrigation water, Abu Tambi said the water quality in the reservoir is excellent and there is no need to worry about hygiene and heavy metals residues. As these fruits are basically exported to Europe, Europe will frequently send people to monitor the water quality of the reservoir, "twice a week to take water samples," to ensure water quality and safety.
Abu Tambi said, "Now take a look at this large pool, water quality do not have to worry about."
In addition, due to the widespread adoption of highly water-saving and smart drip irrigation technology in Israel's agriculture, water consumption is more than 40% less than that of normal irrigation. The fruit trees in Abu Tambi are no exception, and water is not lacking.
Benefiting from the intense sun and abundance of water in the desert, in addition to planting this weed-tolerant jojoba (jojoba oil is famous skin care products), as well as potatoes and a variety of fruits, even Some high-water-consuming plants also grow very good, taste good. As the first country in the world to try to grow crops, Israel's export of fruits is highly competitive. Abu Tambi is also one of the peasants who have made huge gains from it and is now fully capable of continuing to expand the orchard.
Wastewater regeneration:
Mysterious sand in the Shafuddan wastewater treatment plant
The success of Abtapa does not come from personal effort, but the infrastructure is essential for wastewater treatment, transport and storage. However, infrastructure alone is not enough to promote the establishment of this economic model.
"Farmers do not irrigate the treated waste water right from the start," Abbott said.
He said that the mode of export agriculture that is now being irrigated with treated waste water has been established step by step over the years. Various obstacles and the "diastolic" mentality of the audience will take a very long time to overcome. The key word to solve all these problems is "Shafdam," the largest and most advanced wastewater treatment plant in Israel and the Middle East. It is the origin of reclaimed water irrigation.
Shafuddan wastewater treatment plant is located not far south of Tel Aviv, was first built in 1969. When reporters came here, a group of pupils were visiting from the wastewater treatment plant. To cherish the education of water resources, Israel has always paid attention to starting from the baby. Nowadays, Shafdam is not only a wastewater treatment plant, but also has a large exhibition hall resembling the structure of the Aquarium. It also details its history and decontamination mechanism.
Schaffen has many of the world's many wastewater treatment plants have the basic decontamination steps: separated from the large scum, gravitational precipitation of solid sediment, semi-solid organic matter, and then let the wastewater soluble and bacteria in a certain temperature Control each other under the conditions, and most of the decomposition. However, the quality of the treated effluent thus obtained is still not high enough to be used for irrigation. In this regard, Shafdam there is another secret weapon - one of Israel's most: sand.
Reporters came to Shafudan next to a huge container, where smell of waste water has not been heard. The narrator told reporters the principle of sand water purification.
It turns out there are many sand dunes near Shaftean. Aquifers exist beneath the sand dunes. The crude wastewater is injected into this aquifer, allowing it to see through half a year to one year of seepage, which can eventually become very clean.
It should be noted that this process is also confirmed in advance will not be contaminated to other nearby clean water. It is these highly purified wastewaters that made the first batch of educated peasants of the year interested
Ignite Status:
Comparing with Normal Spark Plug, the flame od Iridium Spark Plug spread more frequently. Iridium Spark plug improve much more the ignitability and fuel economy.
Improve Acceleration:
With the 0.5mm center electrode, the acclerating performance improves obviously. The time difference to speed up would be shortened 0.7 to 1 second.
Improve Engine Starting:
With the powerful ignitability, the Iridium Spark plug can ignite the engine easily and make less cut off even under thin air and adverse environment.
